Abstract
The invention discloses a combustible gas induction nozzle and its composite set; air passing the circumference of the nozzle at high speed is utilized to bring away combustible gas in the nozzle to the combustible mixed gas to enter a test container. The combustible gas induction nozzle is simple and convenient to install and satisfied in use effect.
Description
Technical field
The present invention relates to gas and mix, relate in particular to the gatherer under the fuel gas low-pressure state.
Background technology
When using burning mixture to carry out combustion test, fuel gas is flowed to by the examination container in holding vessel, generally be that available evaporimeter formula air supply system or booster pump carry out air feed.This not only need increase many equipment (for example evaporimeter, Cooling and Heat Source pipeline, booster pump) also needs many thermals source.
Summary of the invention
Technical problem to be solved by this invention is: smooth under low-pressure state, the easy importing of fuel gas mixes.
The technical scheme that technical solution problem of the present invention is taked is: the aerodynamics eddy current adsorption effect of utilizing helicla flute nozzle (2) periphery high velocity air to produce, and induce the interior fuel gas " dial-out " of nozzle to get into test chamber and become burning mixture.When periphery at a high speed through the gas time because helicla flute (1) effect produces eddy airstream, under the suction function that eddy airstream produces, the fuel gas that nozzle links to each other in the pipeline (5) flows out naturally.And the pressure reduction of the big more generation of periphery air inlet is just big, and the combustible gas scale of construction of outflow is just many more, otherwise air inlet is little, and pressure reduction is just little, and the fuel gas of outflow is just few.Therefore, through the adjusting of periphery air pressure, flow velocity and the control valve opening size of control combustible gas air supply source, can obtain required a certain proportion of mixed combustible gas bulk concentration that reaches.
The good effect that technical solution problem of the present invention is obtained is:
1, established special " fuel gas is induced nozzle " (2) that make by air intake place, test tube road; Its outer surface is processed with four spiral deep trouths (1) (groove depth 4mm), and the gas that utilizes its periphery to pass through at a high speed directly becomes fuel gas in the nozzle " dial-out " into burning mixture and gets into test chamber;
2, the concentration of burning mixture is controlled through regulating periphery stream pressure, flow velocity and combustible gas burst size size (operation air feed control valve);
3, than adopting booster pump fuel gas " to be squeezed into " other modes such as test chamber and evaporimeter air supply system, experimentation cost significantly reduces, and manufacturing structure is simple, the gas mixed effect is abundant.
Description of drawings
Fig. 1 induces the nozzle part diagram wherein for fuel gas: 1-produces the helicla flute of eddy airstream
Fig. 2 induces nozzle composite set installation diagram wherein for fuel gas: 1-connects pipeline 2-connecting bend 3-connector 4-spiral nozzle
The specific embodiment
With an anticorrosive processing long 100mm nozzle (2); Its outer surface is processed with four spiral deep trouths (groove depth 4mm) (1); After nozzle (2) is connected the fastening connection of pipeline (5) with connector (3), elbow (4); Be installed on coaxial direction center line top in the gaseous mixture air accumulator air inlet, connect pipeline (5) and receive combustible gas container control valve place.
In the time of in working order, (natural air) air-flow that utilizes nozzle (2) periphery to pass through at a high speed gets into the gaseous mixture air accumulator with (linking to each other with flammable container) fuel gas " dial-out " in the nozzle (2) and becomes the mixed combustible gas body.
Regulate nozzle (2) periphery admission pressure flow velocity, rotate combustible gas container control valve opening size, to reach the requirement of a certain proportion of combustible gas desired concn.
Claims (2)
1. a fuel gas is induced nozzle; Its technical characterictic is: a long 100mm (conduit) nozzle (2); Its nozzle outer surface is processed with four spiral deep trouths (1) (groove depth 4mm); (natural air) gas that utilizes its periphery to pass through at a high speed gets into test chamber with fuel gas in the nozzle " dial-out " and becomes burning mixture, to reach the requirement of a certain proportion of combustible gas desired concn.
2. induce nozzle like the said fuel gas of claim (1), it is characterized in that said helicla flute nozzle (2) air inlet one end and the fastening connection of connector (3); Connector (3) other end and connecting bend (4) connect; Connecting bend (4) other end be connected pipeline (5) (being connected to the fuel gas container) and connect; Becoming fuel gas after said four parts assembling induces spray nozzle device to be installed in the middle of the gaseous mixture pipeline air inlet.
